INVENTOR I w a ATORNEY WITNESSES,

T 0 all whom it may concern;

Be it known that I, SAMUEL R. HERRING,

a citizen of the United States, residing at- Delhi, in the county of Richland and State of Louisiana, have invented new and useful Improvements inPlows, of which the following is a specification. The object of the invention is to provide a simple, inexpensive and efficient means whereby a plow shovel or bit may be attached to a plow standard under such conditions as to permit of the removal thereof with facility while insuring thesubstantial holding of the same in operative position when mounted without the use in their connection, as in the ordinary practice, of bolts and similar appliances which are more or less difficult of manipulation, requiring the use of tools, and which being subject to continnal wear in the operation of the device soon become inoperative or ineffective as a means of maintaining the blade in its proper position, and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein:

Figure 1 is a side view of the plow.

Fig. 2 is a sectional view of the same taken longitudinally.

Fig. 3 is a perspective view of one of the wear plates.

Fig. t is a plan view. I Fig. 5 is a transverse section on the plane indicated bythe line 5-5 of Fig. 1.

, (3 is a-detail view of the latch-by means of which the operating bar is held in its shovel locking position.

Fig. 7 is a detail view of the locking bar.

Fig. 8 is a similar view of the clamp.

Supported by the usual plow beam 10 is a standard 11 held in place by means of transverse bolts 12 which extend transversely above and below the beam in con tact with upper and lower wear plates 13 and 1 1, said standard being of looped form, consisting of the side members 15 which are spaced apart to form a guide for a clamp 16 which is pivotally mounted as at 17 upon the standard and is provided at its forward end with rearwardly turned jaw 18 adapted for engagement with an opening 19 in the plow blade or bit 20 arranged upon a seat 21- formed by the front edges of the members of the standard adjacent to the looped portion thereof. The seat is prefer- Specification of Letters Patent. Pate t d J y 13 1920; I Application filed ll/larch 15, 1920. Serial 1a,; 3 651 848. I

ably formed by cutting away a portion of the front edges of said members of the standaid to provide a shoulder 22which bears. I upon the upper edge of the blade or shovel so so that when the clamp is arranged in engaging relation therewith as indicated in. Figs. 1 and 2, the cam faced or beveled inner side of the aw of the clamp serves to crowd the blade upward with its edge against saide5 shoulder to lock the same against displace ment and vibration.

Connected with the projecting rear. end of the clamp member is an operating bar 23 ings or slots 24;.and 25 in said plates 14 and 13, and through a correspondingregisterng opening in the beam, and is provided at its upperend with a grip or handle26 by which the bar may be pulled upward forcibly to cause a firm engagement of the clampmg member with the plow shovel or blade. The operating bar is adapted to be secured in its shovel locking position by means of a latch 27 pivotally mounted as at 2880 upon the plow beam and having a nose 29 for engagement with either of a series of openings 30 in the bar, to suit the thickness of the shovel or blade.

It will be noted that when the clamp mem her is in its engaging positionthe nose or extremity of the jaw thereof after passing through the opening in the shovel or blade liesbetween the side members 15 of the standard, so as to brace the latter againsteo transverse displacement as in order to remove or substitute another blade or shovel it is simply necessary to disengage thelatch from the operating bar and lower the latter so as to withdraw the'jaw of the clamp a pivotal clamp member mounted upon the standard and provided with adownwardly and rearwardly directed jaw for engagement with an opening in a shovel or blade engaging said seat, an operating bar con-* nected with said clamp member and extending slidably through suitable guides on the plow beam, and a latch for. engaging and j which extends upward throughguide open-i7e securing said operating bar With the clamp member in its shovel engaging position.

2. A plow having a looped standard provided with a shovel or blade seat, a clamp for engaging an opening in a shovel or blade arranged upon said seat, an operating bar l0 connected with the rear end of said clamp meniber and extending upwardly through guides on the plow beam, saidbar being provided ith'a plurality of openings, for exposure above the plow beam, and a latch pivotally mounted upon the plow beam and having a nose bearing upon the upper side thereof for engagement With one of said openings in the operating bar for securing the latter with the clamp member inits shovel or blade engaging position.

In testimony whereof I afiix my signature. SAMUEL R.-HERRING.
